l DVD video discs: Digital Versatile Discs that hold world’s standard video.
DVD video discs have adopted “MPEG2”, one of the world standards of
digital compression technologies. The picture data is compressed by 1/
40 on average and stored. Variable rate encoded technology has been
adopted in which the volume of data assigned to the picture is changed
depending on the picture format. Audio data is stored using PCM and
Dolby digital, which enables higher sound. Furthermore, multi-angle and
multi-language features will also help you enjoy the more advanced tech-
nology of DVD video.
l Viewer restrictions: This feature limits what can be viewed in conformity
with the level of restrictions of the country. The level of restrictions varies
depending on the DVD video disc. Some DVD video discs cannot be
played at all, or violent scenes are skipped or replaced with other scenes.
• Level 1: DVD video discs for children can be played.
• Level 2 - 7: DVD video discs for children and G-rated movies can be
played.
